Caption: Timelapse of two telescopes at Mount Wilson Observatory, California, USA. Filmed on a moonlit and starry night. One of the CHARA array telescopes is in the foreground. The 60-inch reflecting telescope is in the background. Operational by 1908, the 60-inch telescope was the first successful large reflecting telescope. Notable astronomers Edwin Hubble and Harlow Shapley each used it for their explorations of space. It is still functioning today and used by amateur astronomers and for education.
